Subdomain redirection for www to non-www

Hi,

My primary webflow domain is permanently pointed to www. I am adding a subdomain, so the url will be xyz.domain.com. This is not pointing to webflow. However, I want both the ‘www.xyz.domain.com’ and ‘xyz.domain.com’ to point only to ‘xyz.domain.com’. I don’t want anyone to visit the www.xyz subdomain.

Since my main domain.com is with webflow, I can’t modify htaccess. How can I achieve www redirect to non-www for my subdomain?
